Leaf burn on peace Lilly

Hi all,

I have a peace Lilly plant and it’s been going well although have recently have noticed increasing burn or discolouration. Not sure what to do about this, think it’s been watered and gets enough sun ok. Any help please?

 

Could be insufficient humidity in the air. That's very common in our homes in winter when we have the heating going, but lots of houseplants are (or are bred from) tropical plants that like high humidity (think jungle conditions).

 

In my experience, Peace Lily leaves always go like that. You can just ignore it or trim the brown bit off, though it will reappear at the new tip. I just remove old leaves every so often.
